The Class Pet from the Black Lagoon

Mrs. Green tells the class that they're going to have a class pet. She's bringing it in from home. Its name is Dina. Will it have fangs, horns, or headlights? Will it be mild or wild? Who knows what kind of pet Mrs. Green will bring in? But when the class sees that Mrs. Green has brought in a hamster, they all really love the cute furry critter.
